This study searched for comparison with geography of Qing China, origin of geographical name, people's feature and costume, description on regional geography, and perception on locality on view of a geographer, Ji-Won Park, a renowned Korean scholar of practical learning on the late 18th century. This study on the first three chapters of his Yorha Ilgi - "Crossing the Amnok(Yalu) River("渡河錄")," "Several Records on Senyang("監京雜識")," and "Writing Essays, Riding Horses("馹迅隨筆")," focusing on landscape of Qing China, inquiry on geographical name, feature and costume, and descriptions on locality, gives a glimpse on Park's geographical view on geography of Qing China. His writing style to compare landscapes between Korea and Qing China, full of his love for Korean landscape, is very delicate and clear, Although he sentimentalized when he passed through Bonghwang-castle(鳳凰城) in China, his subtle and beautiful writing explains that land and mountains in Han-yang(Seoul) are much more wonderful than those in China. His vivid depiction of landscape and weather on his way in Qing China is remarkable and explanation on geographical names like Parhae(渤海), Yoha(遼河), Taejaha(太子河), Senyang(瀋陽) etc. is enough to stimulate readers' curiosity on geography.

This article is about the tradition and history of Baekjesooryukjae(Sooryukjae, one of the Buddhist ritual is called Baekjesooryukjae in Buyeo), which is conducted in Baekje Cultural Festival, the annual festival that is held in Buyeo. Buyeo was a place where various ritual books on Sooryukjae were published, and where Bumpae(Buddhist chants) were taught centering on Mooryang Temple. Based on this tradition, to comfort the lonely spirit of Baekje and pacify the three thousand court ladies, Sooryukjae started to be held 60 years ago. Baekjesooryukjae, unlike Sooryukjae of other regions, have the feature that it is held on the river. In Buyeo, where ritual books were published many times and where there was its own Buyeo education, Sooryukjae is assumed to have been handed down for a long time. Thanks to such historical tradition, Sooryukjae was held as a ritual of pacification in Baekje Cultural Festival. Baekjesooryukjae has unique characteristics. Baekjesooryukjae, which started with the proposal of the residents, shows off its status as the one and only water Sooryukjae that is currently existent, and it shows there are significant meanings depending on the changing venues of 재차 as well as the composition of 재차. It is a Sooryukjae with 60 year-long tradition and locality, history.

Desmodium paniculatum (Fabaceae), native to North America and an alien plant in Japan, was newly found in Hwaseong-si and Daejeon-si, Korea. This species is distinguished from Korean-related taxa based on certain morphological features. Specifically, it is a perennial herb, with a 4-5 jointed loment, and with the basal suture moderately incised between the articles. In the field, D. paniculatum grows around rivers and roadsides, suggesting that it is likely to have been introduced through river improvement work and road construction. On the phylogenetic tree based on an internal transcribed spacer, Korean individuals forms a clade with a Japanese individual. Here, we report a morphological description, photographs, an illustration, and the locality of D. paniculatum.

A goby, Synechogobius hasta (Temminck et Schlegel) was studied to investigate the food consumed and the biological change of the food organisms, and the fish were sampled from the closed tributary and the lower Part of the Naktong River, near Pusan, during the period from November of 1967 to December of 1968. The fish were sampled from four stations (Fig. 1), the total number of fish being 1,295 and they were grouped and analysed monthly. The content of the alimentary canal was analysed in three categories according to modified Nilsson's method (Dahl 1962) with a slight alteration: 1) The number of each item of stomach contents was counted and the percentage of each item in proportion to the total number of food organisms is indicated by the letter 'N' representing numerical percentage in Table 2. 2) The percentage of fish which contained any items of food organisms in proportion to the total number of fish caught in a given season is indicated by the letter 'O' representing frequency of occurrence. 3) Dominant groups of food items were selected and the percentage of the number of each dominant item in proportion to the number of the food organisms belonging to the dominant groups is indicated by the letter 'D' representing dominance. All food organisms were classified in 50 food item categories and then they were grouped in 13 main groups (Fig. 2-1), and they were further divided into 1) obligatory bottom animals, 2) organic drifts and 3) actively swimming forms; according to the conditions of the animal communities within the habitat. Since the majority of its food was composed of the obligatory bottom animals ($94.6\%$), the fish appeard to be a typical bottom feeder. And the dominant food organisms of the fish is generally determined by the local composition of the benthic fauna within the fish habitat. And their seasonal rhythm occurs among the food organisms in the stomach by the biological interaction. Locality variation in the population of the same food organism occurs due to the difference of food organisms in the habitat of the fish at Seonam and Garak, and at Seongsan and Hadan the condition of the niche for the fish in the both regions seems to be the same since the composition and the seasonal variation of the organisms were the same. The results may be summarized as follows: 1) The goby mainly feed on the animals of bottom fauna, and the food organisms are deter-mined by the food compositions within the habitat. 2) Seasonal variation of the stomach content shows the seasonal rhythm due to the biological variation of the population and their interaction. 3) The goby shows no preference on specific food, and the food is composed of a variety of animals. 4) Major food items of the goby are Polychaeta, Palaemon modestus, Isopoda, Gammaridea, Insecta (nymphs and larvae), Ilyoplax deschampsi, and Paratye compressa. 5) Logitudinal succession oil the population of the food organisms is apparently recognized within the community of Seongsan, Garak and Seonam. 6) The goby begins to descend toward the estuary and sea around April when the water temperature reaches $20^{\circ}C$, and they begin to return to river waters in September.

As a part of the epidemiological studies of clonorchiasis, this study was conducted to evaluate the current endemicity and the natural transition of the Clonorchis infection in Gimhae Gun and delta area a high endemic area in Korea in recent years, prior to the introduction of praziquantel which will eventually influence the status of the prevalence. The data obtained in this study in 1983 were evaluated for natural transition of the infection in comparison with those obtained 16 years ago in 1967 by the author(Kim, 1974). The areas of investigation, villages and schools surveyed, methods and techniques used in this study were the same as in 1967, except for the contents of the questionnaire for raw freshwater fish consumption by the local inhabitants. 1) The prevalence rate of clonorchiasis in the general population of the villages was 48.1% on the average out of a total of 484 persons examined. The average of those of the riverside-delta area was 65.2% and 43.0% in the inland area. Among the schoolchildren, the prevalence rate was 8.2% on the average out of a total of 1,423 examined. By area, the prevalence rate was 10.8% in the riverside delta area and 2.8% in the inland area. By sex, difference in the prevalence was seen only in the inhabitants of the inland area showing 52.4% in the male and 33.5% in the female. 2) In the natural transition of the infection, the prevalence rate among the inhabitants has decreased from 68.8% in 1967 to 48.1% in 1983, and in the schoolchildren from 56.4% in 1967 to 8.2% in 1983. The reduction rate was higher in the riverside-delta area than in the inland area. 3) In the prevalence rate by age, 11.9% was first seen in the 5-9 age group and the rate gradually increased up to 75.0% in the 50-59 age group. By sex, the rate was higher in the male than in the female in the 20-29 age group and over. 4) In the natural transition of the prevalence rate by age, the reduction rate of the infection during the past 16 years was greater in the younger age groups up to the 40-49 age group and reached the same level in the age group 50-59. Reduction was seen again in the age group over 60s. By sex, the reduction rate was greater in the female than in the male in the 20-29 age group and over. By area, the reduction rate was greater in the riverside delta area than in the inland area, particularly in the young age groups. 5) In the intensity of the infection among the cases, the mean egg out-put per mg feces per infected cases(EPmg) in the inhabitants was 6.3. EPmg of those of the river-side-delta area was 15.4 and that of the in-land was 2.8. On the other hand, in the schoolchildren, EPmg was 3.2, and no difference was seen between the two areas, the river-side-delta area and the inland area. 6) In the transition of the intensity of the infection by area, EPmg among the inhabitants inexplically increased from 7.8 in 1967 to 15.4 in 1983. This was probably caused by uneven specimen collection in the process of sampling the population. EPmg of the inhabitants in the inland area and those of the schoolchildren of both riverside delta and inland areas showed a similar decrease in the past 16 years. 7) The intensity of the infection by age showed a relatively low level in the 20-29 age group and below, and EPmg 5.1-9.5 was seen in the 30-39 age group and over. Sex, Epmg was 5.8 in the male and 4.7 the female. By in 8) In the transition of the intensity of the infection, EPmg decreased from 6.2 in 1967 to 5.4 in 1983. By age, in contrast to the figures of 1967 in which EPmg gradually increased with some fluctuation from 1.1 in the 0-4 age group to peak 10.5 in the 50-59 age group, in 1983 lower intensity of the infection was seen in the age group from 10-14 to 20-29 with the EPmg range of 0.6-2.7. 9) In the distribution of the clonorchiasis cases by the range of EPmg value, 43.2% of the cases were in 0.1 0.9 and 34.6% in 1.0-4.9. As a whole by cumulative percent, 44.6% of them were under 0.9 as light infection and 86.1% of them under 9.9 up to moderate infection. By sex, no difference was seen in Epmg. 10) In the transition of the distribution by the range of Epmg, the cases were distributed up to the range 80.0-99.9 in 1967 and to 60.0-79.9 in 1983. By cumulative percent, in the range of 0.1-0.9 and less, light infection, 34.3% of them were distributed in 1967 and 44.6% in 1983 with about 10% increase. In the range of 5.0-9.9 and less, up to moderate infection, 83.2% in 1967 and 86.1% in 1983 of the cases were seen, respectively. 11) The practice of raw freshwater fish consumption among the inhabitants seems to have decreased in recent years. Those who admitted to raw freshwater fish consumption in the last two years among the infected inhabitants were 59.3%, although 86.8% of them professed to have experience with raw freshwater fish consumption. 31.7% of those who have had experience of the raw freshwater fish consumption denied any further consumption in recent years. From an interview of 543 school-children, 24.1% of them admitted to an experience of raw freshwater fish consumption. However, those who have practised in the past two years comprized 17.9%. Those who denied raw freshwater fish consumption in recent years among those who had such experience were 26.0% out of 131 interviewed. The rate of raw freshwater fish consumption in both inhabitants and schoolchildren were higher in the male than in the female. On the contrary, the rate of those who did not practise in recent years among those who had experience of raw freshwater fish consumption was higher in the female than in the male. 12) The major reason for the reduction of raw freshwater fish consumption among the local inhabitants was the risk of the fluke infection. However, it has become apparent that such change of taste has resulted from water pollution impact which has affected throughout the areas of the freshwater systems in this locality since last several years. 13) In animal survey, Clonorchis infection was seen in 14.8% of 88 dogs examined and 3.7% of 27 house rats examined. It was noted that populations of dogs and cats have increased in the villages surveyed. Although the prevalence rate was lower in the present survey than those of 1967, the significance of the animals as the reservoir host has not changed. 14) Prevalence rate of Clonorchis infection by cercariae in the first intermediate host, Parafossarulus manchouricus, was 0.6% out of 517 snails examined. The infection rate was lower in comparison with 2.3% out of 2,124 examined in 1967. Moreover, sharp decreases in number and distribution of the intermediate host snails in many watershed areas of the huge freshwater systems in this locality seemed to reduce transmission of Clonorchis in connection with the intermediate host stage of its life cycle. 15) Clonorchis infection in the second intermediate fish hosts was relatively low. The mean number of Clonorchis metacercaria per fish in Pseudorasbora parva was 517 in 1983, whereas it was 1943 in 1968 through 1969. Environmental water pollution has also caused the decreased fish population density in these areas, and this has also apparently affected to the practice of raw freshwater fish consumption among the local inhabitants. 16) In conclusion, endemicity of Clonorchis infection in Gimhae Gum and delta area of the Nagdong River has sharply decreased during the past 16 years. The major cause of the regressive transition of the infection was the water pollution of the land water systems of this locality. The pollution has upset the ecosystems comprizing of the intermediate hosts of Clonorchis in many areas, and also affected to a significant extent to the discontinuance of the local inhabitants for raw freshwater fish consumption.

This study has its purpose on figuring it out to the religious notion in Vietnam with the material of the divinity construction of Den Hang Pho in Sapa where is the northern region of Vietnam. To make this, the study divides the type of Vietnamese temples into four parts; Chua, Den, Dinh, and Mieu. Among them, the study pays attention to 'Den' because Vietnamese historical heroes are seated as divinity. This reason makes a reasonable case to this study to figure out a typically and generally religious faith. First of all, the study analyzes immaculate divinity, which generally consists of three and four layered system. The study confirms that the immaculate divinity started from the goddess and then extended to the concept to dominate the sky, the ground, the sea(river), and the mountain(forest). General Tran Hung Dao is the best historical hero in Vietnam and has been placed in temples called Den. The study exams the context that the divinity extended to the religious beliefs, for examples, the belief related in a childbirth by lots of narrations and ceremonies and the belief to treat a sickness, and also exams the context that the divinity placed in a divinity to make a symmetrical relation with immaculate faith. The study exams the divinity construction of Den Hang Pho as its authentic case. In this case, the study could verify a case emphasized by mountain Holy Mother among immaculate faiths. Especially, the study can confirm that General Tran Hung Dao was apotheosized as a concept to be symmetrized with immaculate divinity, and futhermore, a couple of snakes was emphasized by their positioning to every room. Tri-system lays stress on the aboriginality(locality) centered on minority races in the northern Vietnam, the national identity of Vietnam, and the ecological condition of rivers flowing the valley of high and steep peak. The confirmed facts could be said to a construction what the religious notion of tri-system makes. The study makes a conclusion that this kind of conversion-oriented religious notion naturally corresponded with region, nation, and ecologically environmental condition, and extended to the Vietnamese faith with polytheistic divinity.
